Hey Everyone,
Having a PC-Engine duo-R, what is the best method of backing up internal game save memory? I know Tennokoe Bank cards exist, but they seem to require opening these days and soldering on a new battery. Is there any other alternative that can backup internal saves?
Would a flash cart like the Turbo Everdrive be able to somehow do save game backups?

The Tennokoe Bank 1 works great, I don't think there's a "battery" in there persay.
I believe the internal "battery" is like the one in the Dreamcast - i.e. a rechargeable battery that charges when the system is plugged in. The capacitor unless bad should keep you running.
It gives you 4 Boxes to store data. However, it's not like a typical memory card.
You can only copy over whole banks. So, What I did is move all the saves I want to specific Banks and then copy over that whole bank (box) when I want to play a specific game.
Any issues, just PM me.

There is a lithium button cell in 'em, wynd. My pair still work with the original batteries, but I suppose it's just a matter of time before they croak.
Your only other option is the MB128 (or the functionally identical save kun thingy), which works similarly to a Tennokoe Bank. Instead of a button battery it uses AAs (maybe AAAs?) and it doesn't have its own file utility for swapping banks so you'll need one of the games that has such a utility.
P.S. - no on using a flash cart to back up internal saves.

For the PC-Engine Duo-R capacitor, do you need to have the machine running every day to keep it alive, or does simply having it plugged in work just as well? From what I remember hearing, it only lasts for like a day or so unpowered?

If the cap is draining that quickly, it needs servicing. I think they only need to be plugged in to recharge (system on or off), and they'll last weeks (probably months) before discharging enough to wipe the saves.

I have not been playing my system a lot recently, My Duo R lasted over 2 weeks with saves intact powered off, the first time but somewhere shy of three weeks 3.5 weeks the second time.
